Thanks to all the wonderful feedback I received on this post, I’ve concluded that my Mom’s TiVo has a bad power supply. Instead of trying to buy a power supply to fix the problem, I convinced my Mom that she should pick up a dual tuner TiVo. I really think my Mom is going to like being able to record more then one show at once. The box only costs $100 after a $150 mail in rebate.
Now all I need to is set it up and get her season passes reconfigured….

Do you want to sell the “dead” unit? I may be interested..
If you haven’t bought it yet, the DT unit is only $60 on Amazon (after rebate).
